Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds the concrete return fields, which is useful, but discloses no further behavior such as refresh cadence, aggregation semantics, or what 'settlement pipeline' scopes (per-user, per-network, per-account). No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence that names the resource and then the three returned values. No filler, no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter read tool with no output schema, the description communicates the essential shape of the returned data. It stops short of explaining the settlement domain itself (e.g., what a pending operation means or when settlement completes), which would help an agent interpret the result, but within this tool's scope it is nearly complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so the baseline is 4. The description correctly implies no input is needed by defining the tool purely in terms of outputs.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (get) and resource (settlement pipeline status), then enumerates exactly what is returned: pending operations count, total value queued, and smart account address. This is far more specific than the many sibling 'get_*' tools and lets an agent distinguish it from get_settlement_epochs and get_write_status at a glance.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage (check settlement pipeline state) but never states when to choose this over the closely named get_settlement_epochs, nor any precondition or exclusion. The sibling set is enormous, so the absence of routing guidance is a real but moderate gap.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
